1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → (R)-2-(3,5-dichlorophenylamino)-1-(3-((2-hydroxyethyl)(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)piperidin-1-yl)ethanone

Reaction Steps

To a solution of (R)-2-(piperidin-3-yl(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)ethanol (0.9 mg, 2.2 mmol) in DMF (10 mL) was added EDCI (494 mg, 2.6 mmol), HOBt (351 mg, 2.6 mmol), 2-(3,5-dichlorophenylamino)acetic acid (475 mg, 2.16 mmol) and DIEA (0.574 ml, 3.24 mmol) at 0° C. The solution was stirred at rt over night, diluted with EtOAc (25 mL) and washed with water. The aqueous layer was extracted with EtOAc, dried (Na2SO4) and concentrated in vacuo to give a residue which was purified by column chromatography (silica gel, gradient 0-2% methanol in chloroform) to afford the titled compound (0.4 g, 30%). LCMS [M+1]: 617.
